Control peach crop pests by fruits bagging [Controle de pragas do pessegueiro através do ensacamento dos frutos]

Abstract

Aiming to look for new options of peach bagging in the control of peach insect pests, an experiment was carried out in a tree- year-old peach crop. The cultivar Aurora 2 was accomplished in vase system with 6 m among rows and 4 m among plants. The treatments were: T1 - white and closed TNT (tissue non-tissue) bag (45g/m2), T2 - white and opened TNT bag (45g/m2), T3 - white and closed TNT bag (20g/m2), T4 - white and opened TNT bag (20g/m2), T5 - transparent polypropelene microperfurated and closed bag (1mm of diameter), T6 - transparent polypropelene microperfurated and opened bag (1mm of diameter), T7 - transparent polypropelene microperfurated and closed bags (2mm of diameter), T8 - transparent polypropelene microperfurated and opened bag (2mm of diameter), T9 - milky microperfurated polyetilene and closed bag (1mm of diameter), T10 - milky microperfurated polyetilene and opened bag (1mm of diameter), T11 - milky microperfurated polyetilene and closed bag (2mm of diameter), T12 - milky microperfurated polyetilene and opened bags (2mm of diameter), T13 - closed and waterproof paper bag, T14 - opened and waterproof paper bag, T15 - check treatment (unbagging fruits). According to the results, it may be concluded that all bags are efficient to control fruit flies and birds, but not the oriental fruit moth. The opened bags may be used in peach bagging.
